Some appliances have built in auto-volt transformers that enable them to be used in different countries with different voltage standards for power transmission. Do the auto-volt transformers use a coil spring coupled, motor controlled tap that can change the number of turns from the secondary inductor that the load is connected to depending on the voltage fed to the motor or is it possible to use a solid state control on the auto-volt transformer?
